7 Day average streamflow percentiles compare current stream flows (averaged over the last seven days) to the same seven day period in a site’s historic record. Streamflows are averaged over seven days to minimize the impact of short term fluctuations, and gives a better representation of the overall trend in streamflow. Percentiles give an indication of how likely a seven day streamflow value is; for example, the 50th percentile represents normal conditions, where a streamflow percentile of 10 indicates that this value has occurred only 10% of the time within the history of the site. Data is sourced from real-time and historic Water Survey of Canada data.
In general, a 7 day average streamflow value of:
The below map shows percentiles using both a rolling average over the last seven days of discharge as well as mean discharge over the last 24 hours.
Map data was updated on 23 September 2022, 14:58 PM.
The table below lists all stations with 7 day discharge percentiles below their 10th percentile. If a location is not listed here there are no immediate low streamflow concerns (i.e., 7 day discharge is > 10th percentile).
Regulation Status refers to whether flows are natural or regulated by human activities such as dams; this (as well as the Basin Area) were determined by the Water Survey of Canada.

Environmental flow needs for fish during the summer will range from juvenile rearing flows near 10-20% (preferred) Long-Term Mean Annual Discharge (LT MAD) to adult salmon/char passage flows (>20% LT MAD) required prior to spawning. Sub-standard flows (<10% LT MAD) can affect fish populations by reducing the area and quality of riffle habitats that generate fish food and aeration. Flows nearing 5% LT MAD are considered sub-optimal for fish rearing and migration, indicate a degradation of instream habitat and may require restrictions on water use. A map of realtime streamflow data can be accessed at the BC River Forecast Centre website. LT MAD values were calculated by dividing the 7 day mean discharge by the mean annual discharge (MAD) calculated from historic data. MAD values were calculated for stations with at least 5 years of data in the historic record only from years with complete data using the R package fasstr.
Map data was updated on 23 September 2022, 14:58 PM.
Any stations with LT MAD values of less than or equal to 20% LT MAD are shown in the table below; sites below 5% MAD and 10% MAD are highlighted. The report shows conditions as of today.
Regulation Status refers to whether flows are natural or regulated by human activities such as dams; this (as well as the Basin Area) were determined by the Water Survey of Canada.

The recommended mean weekly maximum temperature (which is the mean of the max daily temperatures from the last seven days) for the protection of all fish species should not exceed 20 degrees C and the maximum daily temperature should not exceed 23degrees C. Reaching either one of these thresholds may trigger fisheries closures and water use restrictions within the affected watersheds. Only a small subset of stations from the Water Survey of Canada collect temperature data in addition to streamflow data; thus the number of sites shown here is much smaller than for streamflow.
Map data was updated on 23 September 2022, 14:58 PM.
The table below shows stations with a 7-day maximum daily temperature (i.e., the max daily temperature from the past 7 days) above 20degC. Also shown are the days from the past week in which the maximum daily temperature exceeded either 20degC or 23degC (critical thresholds for fish health). If no sites are present, all sites with water temperature data show 7-day maximum daily temperatures below 20degC.
Regulation Status refers to whether flows are natural or regulated by human activities such as dams; this (as well as the Basin Area) were determined by the Water Survey of Canada.
